electrical fault maybe

Before you attempt to take out the ignition, call a dealer and ask him if they can get you a key for your bike by using the VIN as reference. Harley and some metrics can do it this way.

.030 to .035

Work like this should start with spending a couple bucks and buying a service manual. Amazon or a bookstore has them reasonable, and will lay out how to disassemble, inspect and most important ,put back together your drive shaft. Without one, it is pretty straight forward, if you're referring to the back seal on the wheel, take stuff off, change seal, put stuff back on, but why the headache when someone already wrote it all down for you? Best $$ you'll ever spend.

starter solinoide not worth trying to repair , replace it !

oil pump is in bottom of engine so engine out , unless you have enough space and a plate that bolts on under side of engine to gain access to it ! ?? have a look !

gear or bearing failed , strip engine !

check coil or wire from coil. could be blown fuse or bad brain...aka CDI in which case you could open it after locating it and possibly discover a bloated capacitor which you can snip off and solder in a new one for 2 bucks. at a radio shack or electronics parts store

it needs to be replaced you cannot fix that.. you may even be able to find a used one at a local junk yard seeing how they may be a little expensive.. let me know how you make out.. and also make sure you clean it well

sidestand lockout switch is sticking...bike thinks that you're trying to ride away with the stand down so it kills the sparks.

I've never been a big fan of automotive oil in a bike. That being said, maybe the Castrol can be used in bikes too I don't know. Anyhow, hopefully someone will be along that can better answer that part of your question. There have been many discussions pertaining to what oil to use. Drop a PM to OilDoc. He can probably answer that question very quickly for you. If this was a car, I'd say that the thermostat was stuck. Maybe start there.

on my bike it is said to be the rectifier, no fixing it just toss and get a new rectifier. its not converting/reducing AC voltage as it should, so higher than spec surplus elec current gets dumped back into the battery, cooking it, also first check your battery ground it may be the problem

Your problem is that your valves are not properly adjusted; had the same problem on my 1985 Ninja 600 - the colder the ambient temperature got the harder it was to start. After a valve adjustment it fired right up even in freezing temperatures very reliably.

capped off the system on my gpz1100e with no wet or winter problems...just as likely to get carb icing on my 900r which has an intact system with new filters...so I wouldn't worry.new filters are cheap enough though if you want to keep the system...

Not likely, but it can kill a battery.

If you have a wiring diagram, trace out the ignition system this way you trace problems. But you could pull the plugs and put them in the wire and ground it against the head, away from the spark plug hole, turn the engine over and see if it fires, i use a spark tester, but a known good plug will do. If there is no spark then check to see if you have volts at the primary side of coil "the little wires that hook to it test them with the ignition on" if no volts there then begin your volt chace checking all wire and connectors. You will need a multi meter ok. let me know how it goes, just takes patience and time k.
